Last Week in WordPress Core

Hi there! Welcome to Last Week in WordPress Core for the week of March 3–9. By now, you’ve heard that WordPress 3.9 Beta 1 is available! Thank you for your hard work this last week. Now we’re done adding new enhancements, and on to bugs. Your help is appreciated as we continue to test and squash bugs on the way to a stable RC.

Admin:

Admin Menu: Introduce a .dashicons-before CSS class and use it in the admin menu. Lets you use a Dashicon before an element without copying the entire .dashicons styling to your :before styling. [27418][27425][27444][27482]#26630

Editor: Show “View Post” for any post the author can read. This expands it to private posts and matches the logic in the toolbar. [27483]#27059

Media:

First pass at bringing the Image Editor into the media modal. Please test me! [27445]#21811

First pass adding a loading indicator to the Media Library. [27438]#24859

TinyMCE:

Add TinyMCE placeholders for audio and video shortcodes and provide a UI to both edit shortcode attributes and replace the src media file in an audio or video shortcode. Also, a flurry of improvements and fixes to them, visible in the full changelog. [27411]#27016

Add a Ctrl+K shortcut to open the linking dialog, which is the “de-facto standard”. [27449]#27305
